Last coupla points.
#1 I plumbed a good sized pond pump with pvc to provide a circular current. At one end of the tank I put a pvc 45 degree angle just under the tanks surface. This shoots a garden hose type of water jet diaganoly down thru the right side of the tank. They love to go play in the current
At the other end of the tank, there is a pipe above the surface parralell with the surface. The two flow in a clockwise motion around the tank. I've valved the 2 pipes so the major pressure goes to the 45 jet current. The above the surface one is a trickle dropping in to help with areating the water.
Besides the play current, (which is a hoot when a small fish goes thru it, it blastes them a foot down stream) is the pond pumps large pre-filter. Due to its' size, provides the best collector of tank crap. When combined with the 3 reverse flow pre-filers, is another reason the tank is so low maintainance.
#2 Buy an auto fish feeder. Not that expensive and nice to have. Thus Im not forced to make time to go feed the fish. They are always hungery, for entertainment purposes, I can choose to go "supplement" their diet. And of course when on vacation or gone on weekends.
#3 Use a light timer to auto turn on the lights. Another nice low maintainance item since the tank is down in the mancave.
When all put together...I dont have to do Jack, but watch them play.
